My `94 toyota camry 2.2L, in the morning starts fine the RPM is at 1100, then when it gets warm it goes dowm to 800 RPMs is that normal or it should stays at least between 900 or 1000RPMs, please somebody...


high idle on starting is normal as it is the same as a choke being on. When it drops back it should be around 900. However tacos in cars are not real accurate under a 1000 rpms so have it checked manually with a rev counter. Run the fault codes to check for a problem.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

2002 dodge neon car idles real high upon starting

I replace the vacuum hose and its still idle


You've got a leak somewhere in the hose, or you left a connection open. You just need to get into it and find it. Not any good way to describe what to do, but the high idle speed is due to a vacuum leak.

Idles too high


This is fairly normal on most cars. It is like the choke. When choked, the idle raises up to increase the internal temperature quicker. Also helps free friction of parts due to the cold. Idle is adjusted by the cars computer and o2 sensors.

Surging and loud whistling noise


Sounds like a vacuum leak. Check all vacuum hoses on the intake, throttle body, etc. Sounds like one cracked or came off. Post back if you have any questions. Hope this helps.
